Efficacy of dexmethylphenidate for the treatment of fatigue after cancer chemotherapy: a randomized clinical trial. [2009.11]
Cancer and its treatment can induce subjective and objective evidence of diminished functional capacity encompassing physical fatigue and cognitive impairment. Dexmethylphenidate (D-MPH; the D-isomer of methylphenidate) was evaluated for treatment of chemotherapy-related fatigue and cognitive impairment...

Double-blind, randomized trial of dexmethylphenidate hydrochloride for the treatment of sarcoidosis-associated fatigue. [2008.05]
BACKGROUND: Fatigue is a common complaint in patients with sarcoidosis. We studied the effectiveness of dexmethylphenidate hydrochloride (d-MPH) in treating sarcoidosis-associated fatigue... CONCLUSIONS: Treatment with d-MPH was associated with a significant improvement in sarcoidosis-associated fatigue. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT00361387.

Clinical Trials Related to Focalin (Dexmethylphenidate)
Study of Dopamine Transporter Receptor Occupancy With Long-Acting Dex-Methylphenidate [Active, not recruiting]
The objectives of this study are to document the pharmacokinetics of the adequacy of DAT
receptor occupancy d-MPH formulation in three doses (20 mg, 30 mg, and 40 mg) using PET
scanning with C-11 Altropane as the ligand across a range of times. It has been estimated
that MPH is effective when the average CNS DAT occupancy is 50% or greater. Focalin XR has
been shown to be clinically effective in an analog classroom as early as 1 hour and as late
as 12 hours. Therefore, it is hypothesized that the average DAT occupancy will be adequate
(50% or greater) at time periods corresponding to the times of clinical efficacy.
The first objective is to examine the onset of action by testing whether average DAT
occupancy will be adequate (50% or greater) at 1 hour after dosing for each dose tested (20
mg, 30 mg, 40 mg).
The second objective is to test the adequacy of average DAT occupancy in a range of later
times for each dose. The times chosen (8, 10 and 12 hours) correspond to times Focalin XR has
been shown to be clinically effective in an analogue classroom study. A range of times have
been chosen since, while effective at 12 hours, the degree of clinical effectiveness
decreased with later time periods. The adequacy of DAT occupancy across this range of time
periods will provide important details on the in vivo molecular action of the medicine at
periods of critical clinical activity.
The third exploratory objective is to examine a time period later then those previously
tested with the highest dose. Since the clinical effectiveness of Focalin XR has not been
tested out to 14 hours, it is unknown whether it is effective at 14 hours. If Focalin XR were
to be effective at 14 hours it would be more likely at the highest dose.
